Three Dimensional Computer Simulation of Pile Foundation for Offshore Wind Turbine
Subject area: Science,Engineering and Technology · Area of research: Wind Turbine
Abstract
Finned pile foundation is used as foundation for offshore wind turbine. The behaviour of fin piles is difficult to explain using simple pile?soil theories or two dimensional numerical analyses because of the complicated geometry of the piles. In the current study, a linear 3D analysis of monopile, finned pile and taper finned pile foundation with an elastic plastic soil model (Mohr-Coulomb), an elastic pile material (steel), cushion model (Mohr-Coulomb) and interface elements are used to model the pile?soil interaction using MIDAS GTS-NX finite element software package. A define soil model represent medium dense sand and hollow steel pile embedded within sand subjected to large lateral loading. Analysis shows that lateral resistance increase if monopile pile is replaced by finned pile and lateral resistance further increases if finned pile replaced by taper finned pile (having taper cross section of fin i.e. major thickness at top and minor at bottom) surrounded with cushion material against lateral loading.
